>> I am an electrical contractor helping hook up one of your hybrid systems ,
>> our State Electrical Inspector would like a explanation of " 24 volt wild AC ".

That just means that 24v is the nominal standard voltage range.

Wild AC means it's 3 phase that varies and jumps around wildly due to windspeed/voltage it makes from 1v to about 48v and it fluctuates with the wind and gust.

It's not bucked, boosted, or contrlled by RPM of the generator as it flows into the controller.

The controller does streamline this in DC voltage going to the batteries.
